Blower no zzle awe  exhaust spreader



A. ''llwCDMPUN BLOWER NOZZLE AND EXHAUST SPREADER Filed March 11,. 1924mounted on the exhaust nozzle body o slot 21 formed inthe threaded shank6 oi the nozzle. `This gives a less flexible adjustment but holds `theparts positively in adjusted positions throughout the range ofadjustment usually required.

The cross web 8 of the spider is made narrow in cross section andtapered to a sharp edge above and below so as to form as small anobstruction as possible to the flow of the exhaust steam. In itsprei'erred form the greatest diameter of the nozzle comes be low its topedge in a position where it stands in the correct relation to the tip 4to produce the spreading action desired. A. tool grip 22 is on the.upper closed end of the plug- 17.

In practice, the spreader nozzle spider is so that the blower` nozzlewill stand concentrie with the exhaust nozzle and the tip l at'- terbeing set on the spider is bolted to the body 3 and the apparatus isready for service. The spreading of both the exhaust and live steamunder control will give the most ellicient exhaust. The device isreadily applicable to existing locomotives and requires no change intheir standard parts.

Though I have described with great particularit'y the details ot theembodiment of the. invention herein shown, it is not to be construedthat am limited thereto, as `Changes in arrangement and substitution otequivalents may be made by those skilled in the art Without departingfrom the invention asdelined in the appended claims.

IIaving thus described my invention, what- I claim as new and desire tosecure by Let ters Patent, is

l. A blower nozzle and exhaust spreader for locomotives, comprising anozzle having a live steam s upply and a jet orice formed between innerand outer members which flare upwardly, and means to mount the blowernozzle in the locomotive exhaust noz zle.

Q'. A blower nozzle and exhaust spreader tor locomotives7 comprising anozzle having a live steam supply and a jet orifice formed between innerand outer members which flare upwardly, and means to mount the blowernozzle with its outer flaring member disposed concentrically in thelocomotive exhaust nozzle.

3. The combination with a locomotive exe haust nozzle. ot a. blowernozzle mounted concentrically therein and having an inverted conicalbody vertically. adjustably mounted within the contracted exhaust nozzle tip and` adapted to spread the exhaust.

4;. The combination with a locomotive exhaust nozzle comprising a bodyportion and a tip of a blower nozzle having a mounting spider adapted tobe held between the exhaust nozzle body and its tip` said blower nozzlehaving an upwardly flaring body adapted to spread the exhaust.

The combination with a loeomoti ve exhaust nozzle comprising a bodyportion and a tip, of a blower nozzle having a mounting spider adaptedto be held between the ex- ,haust nozzle body and its tip. said blowernozzle having an upwardly flaring body adapted to spread the exhaust, alive steam supply tothe blower nozzle. and means on the blower nozzle tospread the live steam jet..

6. A locomotive blower having an eularged chamber at the discharge endol the bore, and a spreader plug screwed into said chamber and haring abottom bore opening into the nozzle bore` and lateral steam outlet portsopening trom its bore into said chamber, the plug forming an adjustabletapering spreader for the steam flowing through said chamber.

In testimony7 whereof I aliix my signature,
